COMMON CODES

FAA-documented squawk meanings

FAA-documented codes include 7500 for unlawful interference, 7600 for radio communications failure and 7700 for emergency, together with additional U.S. special-purpose codes.

SCOPE

Valid code does not always mean special-purpose code

Any four-digit octal Mode A/3 code can be structurally valid, but that does not mean it has a published special-purpose meaning. Codes without a documented meaning are shown as valid octal codes without assigning an interpretation. Arbitrary ATC-assigned codes are not given invented meanings.
